"Utterly shocking levels of incompetence.... I have had bills with incorrect account numbers, bills cancelled and recharged randomly. So far we are three years down the line from the date the accounts should have been closed and I am still receiving incorrect bills. Npower and the Ombudsamn seem to have no interest in giving me the information needed to verify the bills they are sending are correct. Avoid them like the plague, they genuinely seem to have no idea what is going on or how to bill accurately and hope that persistence will wear you down and that you will give in and pay the bill regardless of whether it was owed or not.
